B. Next, the water supply control valve is opened to inject water or hot water from the rinsing nozzle into the entire area of the bath to wash out large dusts in the bath and to moisten the inner surface of the bath.

C. Next, the drain valve is closed, and the spray pump is driven to spray the detergent in the detergent tank from the spray nozzle to the entire area of the bath to adhere the detergent.

D. Next, after a lapse of a certain period of time, the drain valve is opened, the water supply control valve is opened, and water or hot water is sprayed from the rinsing nozzle into the entire area of the bath to wash away the detergent and the dirt decomposed by the detergent.

E. Next, the drain valve is closed, and a filling signal is output to the automatic bath water heater to perform automatic filling.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a bathtub, 2 is a drain port, and 3 is a drain valve. Reference numeral 4 denotes a main body unit, which is installed outside the bathroom and has a detergent tank 5 and a detergent spraying pump 6 incorporated therein.

Reference numeral 7 is a bathroom unit mounted on the edge of the bathtub 1, and the bathroom unit 7 has a drain valve switch 8 for opening and closing the drain valve 3 incorporated therein. Reference numeral 9 is a connecting body that connects the drainage valve switch 8 and the drainage valve 3. 10
Is a detergent inlet provided in the bathroom unit 7, and the detergent injected from the inlet 10 enters the detergent tank 5 through the pipe 11. Reference numeral 12 is a spray nozzle mounted in the bathtub 1, and 13 is a discharge side of the spray pump 6 and the spray nozzle 1.
It is a detergent supply pipe that connects two.

Reference numeral 14 is a rinse nozzle mounted in the bathtub 1, and reference numeral 15 is a water supply pipe with a control valve 16, which is connected to the rinse nozzle 14.

Reference numeral 17 is an automatic bath water heater, and 18 is a reheating circuit.

A controller 19 operated by the remote controller 20 performs the following control.

A. When the cleaning mode switch of the remote controller 20 is turned on, the drain valve opening / closing device 8 is driven to open the drain valve 3 and drain the remaining hot water.

B. Next, the water supply control valve 16 is opened to inject water or hot water from the rinsing nozzle 14 into the entire area of the bath 1 to wash away large dusts in the bath 1 and to moisten the inner surface of the bath 1.

C. Next, the drain valve 2 is closed and the spray pump 6
Is driven to spray and attach the detergent in the detergent tank 5 from the spray nozzle 12 to the entire area of the bath 1.

D. Next, after a certain time has passed, the drain valve 3 is opened, the water supply control valve 16 is opened, and the nozzle 1 for rinsing water or hot water is opened.
It is sprayed from 4 to the entire bath 1 to wash away the detergent and the dirt decomposed by the detergent.

E. Next, the drain valve 3 (and the water supply control valve 1
6) is closed, an automatic hot water filling signal is output to the automatic bath water heater 17, and automatic hot water filling is performed.

[0026]

The effects of the present invention are as follows.

A. The operating cost is low because the detergent is sprayed all over the bath and the chemicals decompose and remove the dirt.

B. Since water or hot water is used only for pre-washing and washing away the detergent, it is effective in saving water.

C. The device can be used with any type of bath water heater.

D. In the device, the drain valve is connected to the opening / closing body in the bathtub, and the spray nozzle and the rinsing nozzle need only be attached to the bathtub by using a suction cup or the like, so the installation work for installation is minimal, especially the existing bathtub. Can be easily attached to.

E. Since it is divided into the main unit and the bathroom unit, the bathroom unit entering the bathroom can be made as small as possible, so it does not get in the way when taking a bath.
